I had been searching in google and here the performance benchmark . Only the Transcoder Addon benchmark I found . First of all The scenario is different 1000 source ( assume they are ip cam with the rtsp link ) - How many startup streams can start in the demo machine below . (only transcoding by wowza ,transrating disabled ) \*\* How many source can be handled by wowza ( without transcoding and transrating , I’ll stream them via ffmpeg ) ( transcoder machine and the streamer machine is different ) \*\*\* Is there any input limit that metered by mbits ? for example , " if I make the performance tuning and give wowza 10gb ram , and Gc is very big with the heap size " Wowza max take 70 Mbit input at the same time etc ? How can I guess the cost , how many machine needed , is there any function or formula for doing this ? OR try and mistake , try again ? _Demo Server_ _Processor: Xeon CPU X5xxx @ 3.xx GHz_ _Cores/Threads: 24/48_ _Memory: 96 GB_ _OS: Windows 7 Enterprise - 64-bit_ _Java: Java 7 64-bit_ _GPU/Acceleration: Single NVidia Tesla C2070 with 6GB RAM_ ---

Hello there, Wowza does not enforce any hard limits. Bandwidth (network throughput) is the usual limiting factor. I believe Java is capable of saturating up to 5 gigs of throughput. With 20% overhead accounted for. A 1g nic = 800mbs throughput, which is 800 1 mbs streams, or 1600 500kbs streams We recommend a late-model dual-quad cpu, 4 - 8 gigs of ram, 64 bit OS and 64bit version of Java. For reference. I hope this information is helpful to you. Please let us know if there is anything else we can assist you with. Salvadore ---

Thanks for the quick response Salvadore . Actual number is 3500 , in a few years it will be 20.000 , I use wowza for along time and developed lots of project , city cameras , conference module etc but it’s the first time that I came across the huge project . A few months ago , I used live-origin,live-edge module and it has really extremely high performance 15.000 current user in 3 machine but there was only one live stream . Multi stream makes me confusion and hard to evaluate what I need .200 is a fine number for the begining , I’ll write to this topic after test.

Hi again , @Salvadore I wanna ask that view counts will be very very low , ie : active stream 300 , active viewers 10 . active stream will be high, in this condition using origin - edge architecture make sense ? I guess I need the opposite tech of live-edge repeater , I need to distribute live streams dynamically , not viewer 😕 > I just realized you are talking about incoming streams, sorry for the confusion. > > 1000 input/source streams on a single server instance is considered extremely high. > > Normally we do not recommend more than 200.

I just realized you are talking about incoming streams, sorry for the confusion. 1000 input/source streams on a single server instance is considered extremely high. Normally we do not recommend more than 200. If they are audio only perhaps that number could be a little higher. You would need consider several Origin servers to handle such a load. You would need to test starting with a low number of input streams and then slowly scale up and monitor the resource usage as you go. Incoming live streams use up several different resources on a system, some memory, some CPU and of course network. It’s probably only a small percent of each of those resources per stream, but have 200 streams and that adds up quickly. Load testing is the best way to know. Salvadore ---

As far as balancing publishers, you may consider setting up multiple instances of Wowza and then utilizing round-robin DNS to distribute the load more evenly across your servers.
